Universal T-cell therapy for treating severe aGVHD

Official title: A Study of Universal CNK-UT Cell Injection in Patients With Refractory Acute Graft-versus-host Disease

Run by First Affiliated Hospital of Zhejiang University · NCT06750133 · Data updated 2026-11-12

This study is testing a new type of T-cell therapy to see if it can help people with severe acute graft-versus-host disease who haven't responded to standard treatments after a stem cell transplant.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 14-70 with grade II-IV steroid-refractory or steroid-dependent aGVHD after stem cell transplantation.

Probably not a fit

Patients with grade I aGVHD or those who are not steroid-refractory may not benefit from this therapy.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This pilot study evaluates the safety and effectiveness of engineered universal T-cells with chimeric natural killer receptors (CNK-UT) in patients suffering from steroid-refractory or steroid-dependent acute graft-versus-host disease (aGVHD) following allogeneic hematopoietic stem cell transplantation. It is a single-arm, open-label, multi-center trial that aims to assess pharmacokinetics and pharmacodynamics of the treatment. Participants will receive the CNK-UT therapy and will be monitored for their response and any adverse effects.

Why it matters

Potential benefit: If successful, this therapy could provide a new treatment option for patients with difficult-to-treat aGVHD.

How similar studies have gone: While there have been studies on T-cell therapies for aGVHD, the specific use of CNK-UT is a novel approach.
